The thing about glowplugs, is that they're not that expensive or difficult to replace, til one of them breaks off in the engine.
Diesel engine question
So is it best to remove glow plugs when the engine is hot after a run? Don't want to snap one.
Squirt if wd40 or similar worth trying?
Have you tried two goes at pre heating the glow plugs before the engine turns over to see if it makes a difference ?
My local garage snapped off the oil dipstick when changing mine . Then charged me for a new one .
Also run PD's into the 300K zone . Does your neighbour have a battery checker ? Could be low on volts or amps making the glow plugs less effective.
Still think its 1 bad plug plus a dry tappet , and at the end of the day so what . It smokes a little on start up , There might be a tiny amount of bore washing from un burnt fuel but its negligable . Summers coming , weather is warming up , making life easier for the battery and starter motor .
Save up a few quid , buy some Bosch glow plugs and whizz em in , nothing really bad is going to happen in the next few thousand miles if you misfire on 1 cyclinder for 3 or 4 engine revolutions.
Not sure it's the glow plugs. If it starts immediately in all weathers, how can it be?
Can you post up a video with sound?
I'll try and get video tomorrow am.
Always fires into life after 1 crank.
Cloud of white smoke
Rough running for max 5 seconds
Then everything is fine - no smoke and idles fine
One or more failed glow plugs so the engine starts on three cylinders with the other one joining in when it gets some heat into it. It's easy to check with a clamp meter.
If you don't mind waiting a couple of days, and have an XP or Win 7 laptop, get a USB diagnostic lead from Ebay, download VCDS-Lite. You'll be able to read your codes. Your generic reader is like mine- doesn't see specific VW codes (there are thousands.)
I would agree with an earlier poster- it sounds like one or more slow plugs to me. You'll be using those plugs much more than you think. Get VCDS, it will make troubleshooting so much easier. The 'shareware' version is free and you'll be enlightened.
I renewed all the glow plugs yesterday for Bosch Duraterm ones.
Started the car this morning and it (as usual) started 1st time.
However the puff if smoke and engine clatter are still there.
So - what next?
Do we just ignore it as it starts and drives fine? Is it a trait of the PD engine?
Dunno about the smoke (although mine is quite smelly on start up), but mine is clattery on start up for a minute or so (1.9 Tdi).
If it's 03 I don't think it will be a PD engine...
White smoke from a TDi Galaxy / Sharran / Alhambra is 99% the Auxilliary heater, under the passenger side rear wheel arch. It's only supposed to try & work below 10degC though. They have a heater plug that burns out. If working fine should sound like a jet engine on a cold day.
For the clattering, watch the aux belt when someone starts the car from cold. They have a clutch type pulley on the alternator. These seize up, & can sometimes take a minute to free up from cold, but usually only when it's idling. It allows the alternator to free wheel. The belt will be jumping around, but then run free. Sounds clattery while it's bouncing. Alternator out to change, & a special tool to change. Several types of pulley, so count the teeth & measure dia before buying.
Other than that, the CAT, loose stuff in there bouncing around ?

Daz or Serviceford are top blokes, & know these cars inside out.
Aux heater works fine. No smoke from that. Just a puff from exhaust on cold start which immediately stops.
I'll check the alternator belt.
Temperature sender,located on the back of the block nearest to the passenger side. Swap out the black original for the green replacement unit. Couple of quid from Eurocarparts. This fools the ecu by giving a false temperature and therefore wrong fuelling at start up.
My dads focus 1.8 tdci would start with all the glow plugs knackered. The injection system is so accurate it still starts but runs like a bag of hammers till it warms up. It would still easily start on one or two plugs but the unburnt diesel would come out as white smoke. Check the wiring they can draw quite a lot of current. Check for signs of burning of the wiring.
My 08 2.0 pd passat does exactly the same as what you describe nomad...
did you get it sorted?
